By an inverter for driving the compressor disposed in the first air-conditioning apparatus, the compressor (11b) is controlled on the basis of a measurement value from at least one of a pressure sensor disposed on the discharge side of the compressor (11b) or an outside air temperature sensor. The amount of refrigerant circulated in the second air-conditioning apparatus is increased compared with the first air-conditioning apparatus.
